Otherwise however I still believe electrical fire in the MEC was the most likely cause. <br /><br />It is fairly obvious from several ATSB reports, particularly the Bayesian Analysis DTSG report published by the ATSB on December 3, 2015 that MH370 suffered electrical failure between 18:03 and 18:43 and then later double engine flame out characteristic of hypoxic flight. What is it about electrical failure however which could cause hypoxia?<br /><br />Fire seems the obvious link but people argue there is no way crew would not have donned oxygen masks, but they miss an important point. <br /><br />When there is smoke in the MEC of a Boeing 777, crew receive an ambiguous EICAS alert stating EQUIP COOLING OVRD which crew had to look up in their QRH handbook. Unconsciousness at 35,000ft takes just 30 seconds. When they reached the relevant page in the B777 QRH it told pilots to wait 2 minutes whilst smoke cleared.<br /><br />Why would smoke clear during that 2 minutes? <br />Because the aircraft was programmed to vent cabin pressure from the MEC. Do that at FL350 and you have a crew unaware that they need to don oxygen masks.<br /><br />When EQUIP COOLING OVRD flashes on the EICAS the aircraft's computer automatically switches air conditioning from AUTO to EQUIP COOLING OVRD then opens a valve to dump cabin pressure all without consulting pilots. <br /><br />This is the simple explanation how MH370 suffered decompression without crew awareness. Pilots never switched off their ACARS or transponder. Electrical failures disabled comms. SAT data was spoofed by electrical failure, fire or even the effect of super-cooling of avionics at 35,000ft.
